According to a first aspect, the invention concerns an image sensor test system (1) that performs processing on an image (I1-I3) supplied by the sensor (1), during which the same operation is performed for each pixel of the image, characterised in that it includes a plurality of processing modules (MT1-MT4), where each module has: a memory that includes an Image zone (I) in which the image is intended to be stored; a processor (P1-P4) connected to the memory and capable of executing the said operation on a group of pixels of the image stored in the Image zone (I). The invention also concerns a process for testing an image sensor (1) that performs processing on an image (I1-I3) supplied by the said sensor, during which the same operation is performed for each pixel of the image, characterised in that it includes stages which: store the said image (I1-I3) in a plurality of processing modules (MT1-MT3); and, in each of the processing modules, execute the said operation on a group of pixels (a, b, c, d) of the said image.

No: 11/992294 Application Filed: September 21, 2006 Claim: 1. An image sensor test system that performs processing on an image supplied by the sensor, during which the same operation is performed for each pixel of the image, the system comprising a plurality of processing modules, where each module comprises: a memory that includes an Image zone in which the image is intended to be stored; a processor connected to the memory and capable of executing the said operation on a group of pixels of the image stored in the Image zone. Claim: 2. A system according to claim 1, wherein the memory of each processing module also includes a Command zone used to indicate to the processor of the said module the group of pixels on which it must execute the said operation. Claim: 3. A system according to claim 1, wherein the processors are each commanded to execute the said operation on a different pixel group of the image. Claim: 4. A system according to claim 1, wherein the memory of each processing module also includes a Program zone in which the said operation is stored in the form of instructions that are executable by the processor of the said module. Claim: 5. A system according to claim 1, wherein the memory of each processing module also includes a State zone in which is stored a state relating to the execution of the operation by the processor of the said module. Claim: 6. A system according claim 1, further comprising an acquisition card connected to the Image zone of each of the processing modules by means of an image bus, so as to perform the simultaneous storage of the image in the Image zone of each of the processing modules. Claim: 7. A system according to claim 1, further comprising a central unit connected to the acquisition card by means of a system bus, with the acquisition card being connected to each module by means of a local bus so that the central unit is able, by means of the system bus and of each local bus, to command the processor of each processing module so that it executes the said operation, and is in possession of the result of execution of the operation by the processor of each module. Claim: 8. A system according to claim 1, wherein the sensor is a CCD or CMOS sensor. Claim: 9. A process for testing an image sensor, that performs processing on an image supplied by the said sensor, during which the same operation is performed for each pixel of the image, the process comprising stages that: store the said image in a plurality of processing modules; and, in each of the processing modules, execute the said operation on a group of pixels of the said image. Claim: 10. The process according to claim 9, wherein the storage stage is effected simultaneously for each processing module. Claim: 11. The process according to claim 9, wherein the execution stage is effected simultaneously with each module. Claim: 12. The according to claim 9, further comprising a stage for passage to each processing module of a parameter relating to the group of pixels to be subjected to the said operation. Claim: 13. The process according to claim 9, further comprising a transmission stage during which each module transmits, to a central unit, a state relating to the implementation of the execution stage. Claim: 14. The process according to claim 13, wherein each module then transfers the result of the said execution stage to the central unit.
